EXTERNAL COMMUNICATION NETWORK TECHNOLOGIES1) Wireless Local Area Networks (WLAN) fixed and reconfigurable (MESH)
2) Cellular networks (GSM, GPRS, UMTS)
3) Two-way paging systems (Paging)
4) Wireless Metropolitan Area Networks (WMAN)PERSONAL COMMUNICATION NETWORKS ON THE BODY

Personal area networks Bluetooth type, were originally designed for connecting laptops, peripherals, PDAs, sensors, mobile phones and all types of devicesthat could be found within walking distance of the person to avoid the hassle of multiple interconnect cables needed. The idea was to provide a reliable wireless system to serve piconet standard forinterconnectivity of these devices together and network access to mobile telephony.
The same concept applies to the situation of wearable systems on the body of the person or included in the clothingand personal items like glasses, wallet, shoes, hat, belt...

Connection systems can be of three types: cables, infrared links and radio networks. At present there are a variety of researchinitiatives and to look for solutions varied. In general it is expected that all systems coexist and diffusion depend on the consolidation of standard products and standards.

1) IrDA (economics,fiability)
2) MIT/IBM PANs ( used the body to communicate, exchange information between people)
3) BODY LAN ( small, low power)
4) Networks in Textiles (siemens, philips, adidas, levis)
5) Bluetooth (bluetooth 2.1 PAPER )
6) BAN
7) ANOTHERS PANS IEEE 802.15
- ZigBee (PAPERS)

THE FUTURE

Wireless communications technologies are evolving very quickly.
The concepts of personalmonitoring and Telecare are converging with other initiatives and visions smart home, home networking, and home automation.

1) UWB (Ultrawideband or Digital Pulse Wireless)
2) X-10
3) CEBus
4) Home...
